WDR91 ELISA kits are immunoassay tools for the measurement of the protein WD repeat domain 91, which is encoded by the WDR91 gene in humans. Functionally, this protein is known to function as a negative regulator of the PI3 kinase/PI3K activity associated with endosomal membranes via BECN1, a core subunit of the PI3K complex. The canonical protein structure is reported to have an amino acid length of 747 residues, a mass of 83.3 kDa, and is a member of the WD repeat WDR91 protein family. It is known to be localized in the membrane. As many as 3 protein isoforms have been reported. Other alias names for this target include SORF-1, SORF1, WD repeat-containing protein 91, and HSPC049.
